Autonomous Uplink (UL) Transmission in New Radio Spectrum Sharing (NR-SS)

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and benefit from US Non-Provisional Patent Application No. 15/649,375, filed July 13, 2017, and US Provisional Patent Application No. 62/446,224, filed January 13, 2017, the entire contents of which are Incorporated herein by reference, as fully set forth below, and for all applicable purposes.

technical field

The present application relates to wireless communication systems and, more particularly, to transmitting uplink (UL) autonomous data in a shared spectrum shared by multiple network operating entities.

Background technique

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing the available system resources (eg, time, frequency, and power). Examples of such multiple-access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, and orthogonal frequency division multiple access (OFDMA) systems (eg, Long Term Evolution ( LTE) system). A wireless multiple-access communication system may include multiple base stations (BSs), each base station simultaneously supporting communication for multiple communication devices (or what may otherwise be considered user equipments (UEs)).

A wireless communication system may operate on a shared spectrum, meaning that the wireless communication system includes one or more frequency bands that may be shared by multiple network operating entities. Shared spectrum may include unlicensed spectrum and/or licensed spectrum. In some examples, multiple network operating entities may share their licensed spectrum with each other to better utilize the spectrum. In some other examples, multiple network operating entities may acquire licensed spectrum together.

The use of the available frequency band spectrum may then be subordinate to a competing process that may involve the use of medium sensing. For example, to avoid interference between different devices or between devices operated by different network operating entities, wireless communication systems may employ medium sensing procedures such as listen before talk (LBT) to ensure that particular channels are Idle before sending a message. The medium sensing process may utilize substantial signaling overhead and may result in increased latency, thus adversely affecting the use of shared spectrum by multiple network operating entities.

One way to reduce medium sensing signaling overhead is to employ a priority-based coordinated access scheme for spectrum sharing. In a priority-based coordinated access scheme, the shared spectrum is divided into time periods. Each time period is designated for a particular type of access. For example, a time period may be allocated to a particular network operator for exclusive access to the shared spectrum, where reservations from the particular network operator are not required. Alternatively, reservations can be utilized to share time slots among multiple network operators on a priority basis. For example, a high priority network operator may have priority or guaranteed access to the shared spectrum during a time slot, but require prior reservation of the time slot. When the high-priority network operator does not reserve a time period, the low-priority network operator can access the shared spectrum in a timely manner within the time period.

Autonomous communications are often timing critical and may have stringent latency requirements. The time division multiplexing (TDM) nature of the priority-based coordinated access scheme may not meet the delay requirements of time-critical traffic. Accordingly, improved procedures for spectrum sharing with autonomous communication support are desired.

Detailed ways

The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations, and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

The techniques described herein may be used in various wireless communication networks, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single Carrier FDMA (SC-FDMA) and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, and the like. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network may implement a wireless technology such as Global System for Mobile Communications (GSM). OFDMA networks can implement wireless technologies such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. . UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are new releases of UMTS using E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used for the wireless networks and wireless technologies mentioned above as well as other wireless networks and wireless technologies, such as next-generation networks (eg, fifth generation (5G) operating in the millimeter-wave band).

One approach to supporting autonomous communication in a priority-based coordinated spectrum sharing scheme is to reserve dedicated frequency bands in the shared spectrum for network operating entities to communicate autonomously (eg, without scheduling). Some examples of autonomous communications may include Ultra Reliable Low Latency Communications (URLLC) traffic and Physical Random Access Channel (PRACH) transmissions. To meet the bandwidth requirements of PRACH transmissions, each dedicated frequency band is required to span a large amount of bandwidth (eg, about 5 megahertz (MHz)). The frequency or bandwidth overhead of dedicated frequency bands is significant when there are multiple network operators. Additionally, when the network operator does not transmit autonomously, dedicated frequency bands are unused and result in medium loss. Therefore, the use of dedicated frequency bands per network operator is inefficient.

Another approach is to reserve a single dedicated frequency band in the shared spectrum for autonomous communication by all network operating entities. The network operating entity may access the dedicated frequency band in time for autonomous communication based on reservations (eg, using request-to-send (RTS) and clear-to-send (CTS) signaling mechanisms). However, the reservation signaling overhead may be excessive when the autonomous communication carries URLLC data that is typically small in size (eg, a few bits or bytes).

This disclosure describes uplink (UL) autonomous transmission mechanisms in a shared spectrum shared by multiple network operating entities. In a priority-based spectrum sharing scheme, the shared spectrum is divided in time into transmission opportunities (TXOPs). Each TXOP is designated for preferential use by priority or high priority network operating entities, and timely use by low priority network operating entities based on reservations. In one embodiment, the TXOP may include dedicated resources for UL autonomous transmissions. The TXOP can be configured with dedicated resources based on the duty cycle. For example, a dedicated resource may be a dedicated frequency band in a shared spectrum, where the dedicated frequency band is shared by multiple network operating entities. Alternatively, the dedicated resource may be a time period within a TXOP that is allocated to the priority network operating entity for that TXOP. In another embodiment, a node of a particular network operating entity may send UL autonomous data in a TXOP concurrently with a transmission to another network operating entity that has reserved or gained access to the TXOP. The transmit power level of UL autonomous data may be controlled via interference management. In another embodiment, the network operating entity may reserve a TXOP for UL autonomous communication without knowing whether a TXOP is required.

The present disclosure may provide several benefits. For example, the allocation of dedicated resources in TXOPs for UL autonomous transmissions can reduce transmission delays for timing-critical data. The use of dedicated frequency bands among multiple network operating entities or among the time portions of TXOPs for UL autonomous transmissions may improve resource utilization efficiency. The use of interference management to take into account simultaneous UL autonomous transmissions of one network operating entity and other transmissions of another network operating entity, and thus can reduce the transmission delay of time-critical data. The additional reservation for UL autonomous communication can also improve the transmission delay of time-critical data. The disclosed embodiments are applicable to coverage areas including macro cells and small cells. The disclosed embodiments are compatible with any wireless communication protocol.

1 illustrates a wireless communication network 100 in accordance with an embodiment of the present disclosure. Network 100 includes BS 105 , UE 115 and core network 130 . In some embodiments, the network 100 operates on a shared spectrum. The shared spectrum may be unlicensed or partially licensed for one or more network operators. Access to the spectrum may be limited and may be controlled by a separate coordinating entity. In some embodiments, network 100 may be an LTE network or an LTE-A network. But in still other embodiments, the network 100 may be a millimeter wave (mmW) network, a new radio (NR) network, a 5G network, or any other successor network to LTE. The network 100 may be operated by more than one network operator. Radio resources may be divided and arbitrated among different network operators for coordinated communications between network operators on the network 100 .

BS 105 may communicate wirelessly with UE 115 via one or more BS antennas. Each BS 105 may provide communication coverage for a respective geographic area 110 . In 3GPP, the term "cell" may refer to that particular geographic coverage area of a BS and/or a BS subsystem serving that coverage area, depending on the context in which the term is used. In this regard, the BS 105 may provide communication coverage for macro cells, pico cells, femto cells, and/or other types of cells. A macro cell typically covers a relatively large geographic area (eg, several kilometers in radius), and may allow unrestricted access by UEs with service subscriptions with the network provider. A pico cell can typically cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions with the network provider. A femtocell can also typically cover a relatively small geographic area (eg, a residence), and in addition to unrestricted access, it can also provide access by UEs with an association with a femtocell (eg, in a closed user Restricted access by UEs in a group (CSG), UEs for users in residences, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in Figure 1, BS 105a, BS 105b, and BS 105c are examples of macro BSs for coverage areas 110a, 110b, and 110c, respectively. BS 105d is an example of a pico BS or a femto BS for coverage area 110d. As will be appreciated, the BS 105 may support one or more (eg, two, three, four, etc.) cells.

The communication link 125 shown in the network 100 may include uplink (UL) transmissions from the UE 115 to the BS 105 or downlink (DL) transmissions from the BS 105 to the UE 115 . UEs 115 may be dispersed throughout network 100, and each UE 115 may be stationary or mobile. UE 115 may also be referred to as a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal , remote terminal, handheld device, user agent, mobile client, client, or some other appropriate term. UE 115 may also be a cellular telephone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, tablet computer, notebook computer, cordless telephone, personal electronic device, handheld device, personal computer, wireless local loop (WLL) ) stations, Internet of Things (IoT) devices, Internet of Everything (IoE) devices, Machine Type Communication (MTC) devices, appliances, automobiles, and more.

BS 105 may communicate with core network 130 and with each other. Core network 130 may provide user authentication, access rights, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. At least some of the BSs 105 (eg, which may be examples of Evolved Node Bs (eNBs) or Access Node Controllers (ANCs)) may communicate with the core network 130 via backhaul links 132 (eg, S1, S2, etc.) A connection is made, and wireless configuration and scheduling for communications with the UE 115 can be performed. In various examples, the BSs 105 may communicate with each other directly or indirectly (eg, through the core network 130 ) via backhaul links 134 (eg, X1, X2, etc.), which may be wired communication links or wireless communication link.

Each BS 105 may also communicate with multiple UEs 115 through multiple other BSs 105, which may be an example of an intelligent radio head. In alternative configurations, the various functions of each BS 105 may be distributed across the various BSs 105 (eg, wireless head-end and access network controller) or integrated into a single BS 105.

In some implementations, the network 100 utilizes Orthogonal Frequency Division Multiplexing (OFDM) on the downlink and Single-Carrier Frequency Division Multiplexing (SC-FDM) on the UL. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal sub-carriers, which are also commonly referred to as tones, bins, and so on. Each sub-carrier may be modulated with data. Typically, modulation symbols are sent using OFDM in the frequency domain and SC-FDM in the time domain. The spacing between adjacent subcarriers may be fixed, and the total number (K) of subcarriers may depend on the system bandwidth. The system bandwidth can also be divided into subbands.

In an embodiment, BS 105 may allocate or schedule transmission resources (eg, in the form of time-frequency resource blocks) in network 100 for DL and UL transmissions. Communication may be in the form of radio frames. A radio frame may be divided into a plurality of subframes, eg, about ten. Each subframe may be divided into slots, eg, about 2. In frequency division duplex (FDD) mode, simultaneous UL and DL transmissions can occur in different frequency bands. For example, each subframe includes a UL subframe in the UL frequency band and a DL subframe in the DL frequency band. In time division duplex (TDD) mode, UL transmission and DL transmission occur in different time periods using the same frequency band. For example, a subset of subframes in a radio frame (eg, DL subframes) may be used for DL transmissions, and another subset of subframes in a radio frame (eg, UL subframes) may be used for UL transmissions .

DL subframes and UL subframes can be further divided into several regions. For example, each DL subframe or UL subframe may have a predefined region for transmission of reference signals, control information, and data. A reference signal is a predetermined signal that facilitates communication between the BS 105 and the UE 115 . For example, the reference signal may have a specific pilot pattern or structure, where the pilot tones may span an operating bandwidth or frequency band, all at predefined times and predefined frequencies. For example, the BS 105 may transmit cell-specific reference signals (CRS) and/or channel state information-reference signals (CSI-RS) to enable the UE 115 to estimate the DL channel. Similarly, UE 115 may send sounding reference signals (SRS) to enable BS 105 to estimate the UL channel. Control information may include resource allocation and protocol control. The data may include protocol data and/or operational data. In some embodiments, BS 105 and UE 115 may communicate using self-contained subframes. A self-contained subframe may include a portion for DL communication and a portion for UL communication. Self-contained subframes may be DL-centric or UL-centric. A DL-centric subframe may include a longer duration for DL communication compared to UL communication. A UL-centric subframe may include a longer duration for UL communication as compared to UL communication.

In an embodiment, UE 115 attempting to access network 100 may perform an initial cell search by detecting a primary synchronization signal (PSS) from BS 105 . The PSS may enable synchronization of period timing and may indicate a physical layer identification value. The UE 115 may then receive a secondary synchronization signal (SSS). The SSS may enable radio frame synchronization and may provide a cell identification value, which may be combined with a physical layer identification value to identify a cell. SSS can also enable detection of duplex mode and cyclic prefix length. Some systems, such as TDD systems, may send SSS but not PSS. Both PSS and SSS may be located in the center portion of the carrier, respectively. After receiving the PSS and SSS, the UE 115 may receive a master information block (MIB), which may be sent in a physical broadcast channel (PBCH). The MIB may contain system bandwidth information, system frame number (SFN) and physical hybrid ARQ indicator channel (PHICH) configuration. After decoding the MIB, UE 115 may receive one or more system information blocks (SIBs). For example, SIB1 may contain cell access parameters and scheduling information for other SIBs. Decoding SIB1 may enable UE 115 to receive SIB2. SIB2 may contain Radio Resource Configuration (RRC) related to Random Access Channel (RACH) procedures, paging, Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Power Control, SRS and Cell Barring ) configuration information. After obtaining the MIB and/or SIB, the UE 115 may perform random access procedures to establish a connection with the BS 105 . After the connection is established, the UE 115 and the BS 105 may enter a normal operational phase in which operational data may be exchanged.

In some embodiments, UE 115 and BS 105 may be operated by multiple network operators or network operating entities, and may operate in a shared radio frequency spectrum, which may include licensed or unlicensed frequency bands. Shared spectrum may be divided in time for sharing among multiple network operating entities to facilitate coordinated communications. For example, in network 100, BS 105a and UE 115a may be associated with one network operating entity, while BS 105b and UE 115b may be associated with another network operating entity. By dividing the shared spectrum in time according to the network operating entity, communication between BS 105a and UE 115a and communication between BS 105b and UE 115b can both occur during respective time periods and can be made to utilize designated of the entire spectrum in the shared spectrum. Additionally, certain time periods may be allocated for certain types of communications or access on the shared spectrum. Further, certain resources may be allocated for autonomous transmissions or to cover autonomous transmissions to meet latency requirements for timing-critical data (eg, Physical Random Access Channel (PRACH) preamble or Scheduling Request (SR)), as described in more detail herein.

To support coordinated access to the shared spectrum, the BS 105 or an entity of the core network 130 may act as a central arbiter to manage access and coordinate the allocation of resources among the different network operating entities operating within the network 100 . In some embodiments, the central arbiter may comprise a Spectrum Access System (SAS). Additionally, transmissions from multiple network operating entities may be time synchronized to facilitate coordination.

2 illustrates an example of a wireless communication network 200 that supports priority-based spectrum sharing in accordance with an embodiment of the present disclosure. Network 200 may be similar to network 100 . For the purpose of simplifying the discussion, FIG. 2 shows three BSs 205 and four UEs 215 , but it will be appreciated that embodiments of the present disclosure may be extended to more UEs 215 and/or BSs 205 . BS 205 and UE 215 may be similar to BS 105 and UE 115, respectively. BS 205a serves UE 215a in macro cell 240. BS 205b serves UEs 215b and 215d in pico cell 245 within the coverage area of macro cell 240. BS 205c serves UE 215c in another pico cell 250 within the coverage area of macro cell 240. BS 205 and UE 215 may communicate on the same spectrum.

Due to the different transmission power requirements or power classes of nodes (eg, BS 205 and UE 215) in macro cell 240 and pico cell 245 and pico cell 250, different power class nodes may be treated as different network operating entities, and The allocations have different priorities for sharing the spectrum to minimize interference. For example, BS 205a and UE 215a may be treated as one network operating entity (eg, operator A), and BS 205b and BS 205c and UEs 215b-d may be treated as another network operating entity (eg, operator B). In this disclosure, the terms network operating entity and operator may be used interchangeably and may be associated with a particular priority and/or a particular power class.

The spectrum may be divided by classifying temporal resources into time periods and assigning these time periods to different network operating entities. In some embodiments, certain time periods are allocated for exclusive use by particular network operating entities. Other time periods may be allocated for preferential use or guaranteed use by particular network operating entities, but may also be used for timely use by other network operating entities. In yet other examples, certain time periods may be designated for timely use by all network operating entities, eg, to enable the addition of network operating entities to network 200 in a decentralized manner. The requirement for a time slot to be preferential use or timely use may be reservation based. Additionally, certain resources may be allocated for autonomous communications by all network operating entities or by specific network operating entities. Further, by managing interference, autonomous communications of one network operating entity may occur concurrently with other communications of another network operating entity. The autonomous communication mechanism is described in more detail herein.

3 illustrates a priority-based spectrum sharing scheme 300 according to an embodiment of the present disclosure. The x-axis represents time in some constant units. The y-axis represents frequency in some constant units. Scheme 300 may be employed by BS 105 and BS 205 and UE 115 and UE 215. Although scheme 300 illustrates coordinated spectrum access for two different network operating entities (eg, operator A and operator B), scheme 300 may be applied to any suitable number of network operating entities.

In scheme 300 , the shared spectrum on frequency band 340 is divided in time into superframes 302 . Each superframe 302 is divided into exclusive access periods 304 and TXOPs 306 . Each TXOP 306 includes a plurality of channel sensing or clear channel assessment (CCA) periods 308 at the beginning of the TXOP 306 , followed by a transmission period 310 . The exclusive access period 304, the CCA period 308, and the transmission period 310 may have fixed durations. For example, each exclusive access period 304 may include one or more subframes, each CCA period 308 may include one or more OFDM symbols, and each transmission period 10 may include one or more subframes. In some embodiments, superframe 302 may correspond to one radio frame (eg, approximately 10 milliseconds (ms) long), and each TXOP 306 may have the granularity of time slots 314 (eg, approximately 500 microseconds (μs) long), And each exclusive access period 304 may span approximately 2 time slots 314 (eg, 1 millisecond long). The structure of the superframe 302 is predetermined and known to all network operating entities sharing the shared spectrum. When operating in the shared spectrum, the network operating entities may be time synchronized.

Each exclusive access period 304 is designated for exclusive use by a particular network operating entity. For example, the exclusive access period 304a is designated for exclusive communication 321 by operator A. Operator B is not allowed to transmit during the exclusive access period 304a. Similarly, the exclusive access period 304b is designated for exclusive communication 331 by operator B, and operator A is not allowed to transmit during the exclusive access period 304b. In an embodiment, the exclusive access period 304 may be used for acquisition and signaling of PSS, SSS, PBCH, SIB, paging, RACH, and/or timing critical data. In some other embodiments, the exclusive access period 304 may be divided into regions, eg via time division multiplexing (TDM) or frequency division multiplexing (FDM), each region designated for exclusive use by a particular network operating entity usage of.

Each CCA period 308 in the TXOP 306 is assigned to a particular network operating entity. For example, CCA period 308a and CCA period 308b are allocated to operator A and operator B, respectively. The number of CCA periods 308 in the TXOP 306 may be dependent on the number of network operating entities in the network. For example, a network with N network operators may include up to N CCA periods 308 in the TXOP 306 . The CCA period 308 may be scheduled in the TXOP 306 based on the communication or access priority of the network operating entities (eg, in descending order). Thus, each TXOP 306 is prioritized for use by the highest priority network operating entity, and each TXOP 306 may be utilized on a timely basis by a lower priority network operating entity if the resource is not utilized by the prioritized network operating entity of. Additionally, the priorities of the network operating entities may be rotated among the TXOPs 306 within the superframe 302 (eg, in a round-robin fashion).

As shown, TXOP 306a is designated for prioritized communications 322 by operator A and timely communications 332 by operator B. TXOP 306b is designated for prioritized communications 333 by operator B and timely communications 323 by operator A. Prioritized communication refers to the use of guaranteed resources, while timely communication refers to the timely use of resources not reserved by high-priority operators.

For example, an operator A node (eg, BS 205a) may send a reservation request (RRQ) signal in the CCA period 308a of the TXOP 306a to reserve a subsequent transmission period 310a, and in the transmission period 310a with another An operator A node (eg, UE 215a) communicates. The RRQ signal may include a predetermined preamble sequence or an RTS signal. In some embodiments, the target receiving node may respond to the RRQ signal by sending a reservation response (RRS) signal or a CTS signal. In some embodiments, the RRQ signal may include scheduling (eg, DL triggers and/or UL grants) for the transmission period 310a. This schedule may be referred to as a regular schedule. Operator Node Bs (eg, BS 205b and UE 215b) may listen to the channel during CCA period 308a. When detecting RRQ signals and/or RRS signals from the operator A node, the operator B node may avoid using the transmission period 310a. However, when no reservation is detected in the CCA period 308a, the operator Node B (eg, BS 205b) can use the transmission period 310a in time by sending the reservation in the CCA period 308b of the TXOP 306a, and in the transmission period 310a communicates with another operator Node B (eg, UE 215b).

6-9 illustrate various UL autonomous data transmission mechanisms based on the superframe 302 structure of the scheme 300 and may be employed by BS 105 and BS 205 and UE 115 and UE 215. 6-9 illustrate UL autonomous communications by two operators (eg, operator A and operator B) for simplicity of discussion, it will be appreciated that embodiments of the present disclosure Can be expanded to more UEs 215 and/or BSs 205. In Figures 7-9, the x-axis represents time in some constant units, and the y-axis represents frequency in some constant units.

6 illustrates a UL autonomous transmission scheme 600 according to an embodiment of the present disclosure. In scheme 600, network operating entities (eg, BS 105 and BS 205) may reserve for UL autonomous transmission regardless of whether any UE (eg, UE 115 and 215) has UL autonomous data for transmission some of the TXOPs 306 (eg, based on a certain duty cycle). For example, operator A has a higher priority than operator B in TXOP 306a. At step 610, for example, the BS 205a may determine the TXOP 306a to reserve for UL autonomous transmission based on a predetermined duty cycle. At step 620, the BS 205a may transmit RRQ and/or RRS signals during the CCA period 308a of the TXOP 306a to reserve the TXOP 306a. At step 630, the BS 205b may monitor the CCA period 308a. At step 640, upon detecting RRQ and/or RRS signals from BS 205a, BS 205b may yield access to high priority BS 205a and avoid using TOXP 306a. At step 650, if the UE 215a has UL autonomous data for transmission, the UE 215a may send the UL autonomous data to the BS 205a during the reserved TXOP 306a. However, if UE 215b does not have UL autonomous data ready for transmission, TXOP 306a may be left unused.

By reserving TXOPs 306 for UL autonomous communications, scheme 600 provides additional transmission opportunities for RACH data, URLLC data, and/or timing-critical data, rather than limiting autonomous in the allocated exclusive access period 304 transmission. Therefore, scheme 600 can satisfy the latency requirement for autonomous transmission. However, TXOP 306 is reserved without prior knowledge of whether there is UL autonomous data from the UE. Therefore, scheme 600 may reserve more TXOPs 306 than required. Additionally, the reservation of the TXOP 306 prevents other network operating entities (eg, operator B) with data for transmission during the reserved TXOP 306 when there is no UL autonomous data in the reserved TXOP 306 Use medium. Therefore, scheme 600 may be inefficient in resource utilization.

7 illustrates a UL autonomous data transmission scheme 700 in accordance with an embodiment of the present disclosure. Scheme 700 allocates or configures a portion of frequency resources in the shared spectrum based on a duty cycle (eg, at every 5 milliseconds) for all network operating entities to transmit UL autonomous data. For example, in some TXOPs 306 , the frequency band 340 that shares the spectrum is divided into two frequency bands 342 and 346 . Band 342 and band 346 may be separated by guard band 344 to mitigate adjacent band interference. The configuration of frequency band 342 and frequency band 346 is known to all network operating entities. As described in scheme 300, frequency band 342 may be shared by multiple network operating entities for regular communications based on priority and reservation. For example, operator A may have preferential access for regular communication on frequency band 342 in TXOP 306a, while operator B may have timely access for regular communication on frequency band 342 in TXOP 306a .

Band 346 is a dedicated frequency band designated for UL autonomous data transmission by all network operating entities. Band 346 may occupy a portion of band 340 . In an embodiment, the frequency band 346 may span a bandwidth sufficient for PRACH transmission (eg, about 5 MHz). Network operating entities may contend for resources in frequency band 346 for transmitting UL autonomous data. In an embodiment, the UL autonomous data is a PRACH preamble, where different network operating entities can be distinguished by using different PRACH preamble sequences. It should be noted that the CCA period 308 spans the entire frequency band 340 . Therefore, UL autonomous communication may occur during transmission period 310 and not during CCA period 308 .

For example, BS 205a (eg, operator A) has gained access to TXOP 306a by employing the reservation mechanism described in scheme 300, and uses TXOP 306a for both DL and UL communications. The transmission period 310a is divided into a number of consecutive DL subframes 702 followed by a number of UL consecutive subframes 704 in the shared frequency band 342 . Each DL subframe 702 or UL subframe 704 may have the granularity of slot 314. Each DL subframe 702 may include a DL control portion 705 and a DL data portion 706 . The last DL subframe 702 may further include a UL control section 707 . The first UL subframe 704 may include a DL control portion 705 and a UL data portion 708 . Subsequent UL subframes may include UL data portion 708 .

In each DL subframe 702, the BS 205a may transmit DL control 710 in the DL control section 705 and DL data 712 in the DL data section 706. DL control 710 may indicate DL resource allocation or scheduling information for the following DL data portion 706 . DL data 712 may be sent according to a DL resource allocation. DL data 712 may be referred to as scheduled DL data or regular DL data, which may not be timing critical. In the last DL subframe 702, the UE 215a may send UL control 714 in the UL control section 707. UL control 714 may indicate scheduling request (SR), hybrid automatic repeat request (HARQ) information, and/or channel quality indicator (CQI) information.

In the first UL subframe 704, the BS 205a may send DL control 720 in the DL control portion 705 to indicate UL resource allocation or scheduling information in the following UL data portion 708 or UL subframe 704. For example, the BS 205a may schedule the UE 215a to transmit in the next UL data portion 708. Accordingly, UE 215a may transmit UL data 724 in UL data portion 708 based on the schedule. UL data 724 may be referred to as scheduled UL data or regular UL data, which may not be timing critical.

During transmission period 310a, when the serving BS is not in an active transmission, the UE may contend to send UL autonomous data in frequency band 346. The UE may determine whether the serving BS is active or has gained access to a particular TOXP 306 by monitoring the channel (eg, the shared spectrum) during the CCA period 308 . When the serving BS has access in a particular TXOP 306, the UE may detect the CRS and DL control information to determine the format of the transmission period 310 (eg, the positions of the DL subframe 702 and the UL subframe 704). For example, UE 215a or another UE served by BS 205a may monitor CCA period 308a and determine that BS 205a is active during transmission period 310a. Accordingly, UE 215a or another UE may contend to transmit UL autonomous data 730 in frequency band 346 at any time during UL subframe 704 .

When the UE determines that the serving BS is inactive during the particular TXOP 306, the UE may contend to transmit UL autonomous data in the frequency band 346 at any time during the transmission period 310 of the particular TXOP 306. For example, UE 215b or another UE served by BS 205b may monitor CCA period 308 and determine that BS 205b is inactive in TXOP 306a. Accordingly, UE 215b or another UE may contend to transmit UL autonomous data 732 in frequency band 346 at any time during transmission period 310a. As shown, UL autonomous data 732 is sent during DL subframe 702 .

8 illustrates a UL autonomous data transmission scheme 800 in accordance with an embodiment of the present disclosure. Scheme 800 allocates or configures a portion of resources at the beginning of some TXOPs 306 based on the duty cycle for the corresponding prioritized network operating entity to transmit UL autonomous data. For example, the transmission period 310 of the TXOP 306 may be divided into two parts 802 and 804 . In the absence of a previous reservation, the portion 802 at the beginning of the transmission period 310 is designated for UL autonomous transmission by the corresponding prioritized network operating entity. As described in scheme 300, portion 804 may be shared by multiple network operating entities for regular communications based on priority and reservation. For example, operator A has a higher priority than operator B in TXOP 306a. Accordingly, portion 802 may be used by an operator A node (eg, UE 215a) to transmit UL autonomous data. In portion 804, operator A may have preferential access for regular communications, while operator B may have timely access for regular communications.

For example, UE 215a may transmit UL autonomous data (eg, PRACH preamble) 810 during portion 802 regardless of whether BS 205a has reserved TXOP 306a. If BS 205a does not reserve TXOP 306a, BS 205b may reserve TXOP 306a for regular communication in due course. However, the BS 205b needs to free up the portion 802 for UL autonomous communication by operator A. As shown, BS 205b communicates regular or scheduled data 820 with UE 215b in portion 804 .

9 illustrates a UL autonomous data transmission scheme 900 in accordance with an embodiment of the present disclosure. Scheme 900 allows a network operating entity to send UL autonomous data in a TXOP 306 regardless of whether another network operating entity reserves the TXOP 306 for communication. Scheme 900 manages interference so that UL autonomous data transmissions may cause little or no interference to conventional communications. In FIG. 9, patterned squares represent transmitted signals, and empty squares represent received signals. A dashed square is included as a reference to the structure of the TXOP 306 frame structure without signaling or reception. For example, operator A has a higher priority than operator B in TXOP 306a. The BS 205a may send the RRQ signal 910 in the CCA period 308a to reserve the transmission period 310a for DL communication with the UE 215a. UE 215a may detect RRQ signal 910 and respond with RRS signal 912. BS 205a may also send RRS signals when BS 205a expects to receive UL transmissions. Subsequently, the BS 205a and the UE 215a may continue normal communication during the transmission period 310a. For example, BS 205a and UE 215a may transmit DL signals 914 (eg, DL control signals 710 and DL data signals 712) and UL signals 916 (eg, UL control signals 714) in transmission period 310a.

In one embodiment, the UE 215b may listen to the medium (eg, the shared spectrum) during the CCA period 308 and may detect the RRQ signal 910 and/or the RRS signal 912 from operator A. When the UE 215b has UL autonomous data (eg, PRACH preamble) 920 for transmission, the UE 215b may send the UL autonomous data 920 in the transmission period 310a while the BS 205a exchanges regular communications with the UE 215a, and depends on the operator Interference cancellation of A to cancel the interference caused by the transmission of UL autonomous data 920.

In another embodiment, the UE 215b may determine the maximum allowable transmit power level for UL autonomous transmissions based on the received signal power of the RRQ signal 910 and/or the RRS signal 912. UE 215b may transmit UL autonomous data 920 at a lower power level (eg, according to the determined maximum allowable transmit power level) to reduce or minimize interference to operator A's regular communications. BS 205a may receive and decode UL autonomous data 920. It should be noted that the PRACH preamble can be detected at substantially lower power levels.
